FACING-IRON FOR WAGON-BODIES.

SPECIFICATION forming part of Letters Patent No. 231,050, dated August 10, 1880.

Application filed April 13, 1880.

To all whom it may concern:

' bodies, &c.; and it consists in rolling in them countersinks.

countersinks for the securing-nails just as they leave the last forming-rolls, and before they have cooled.

In the drawings, Figure 1 is a section of a pair of rolls and a portion of a facing-iron on its way through the rolls and receiving its Fig. 2 is a broken section of one corner of a wagon-body, giving a side view and crossseotion of the facing-iron. Fig. 3 is a plan of one of my irons.

Heretofore facing-irons have been perforated and countersunk at different operations, and the perforations have been so much larger than the nails that the irons, after the body had been in use for a short time, would not be held firmly against lateral displacement. The object of my invention is to overcome this difficulty and at the same time render the production of facing-irons more rapid and cheaper. A

(No model.)

A is a facing-iron. A is an iron in process of receiving its countersinks from the teats b of the roll B.

The countersinks may extend sufliciently into the metal to slightly perforate it; but I contemplate placing the rolls B B sufficiently far apart to leave about one thirty-second of an inch of the metal unperforated. In either case each securing-nail may be easily driven through, will carry with it a burr, a, as shown in Fig. 2, and will fit tightly therein, so as to secure the iron against all lateral strain.

The rolls B B receive the irons from the last forming-rolls while still hot, and therefore no reheating of them is necessary.

By my invention I produce a better facingiron and reduce the cost of ironing a body between five and fifteen cents apiece.

I claim As a new article of manufacture, the rolled bar for facing-irons, provided at intervals with countersinks, and having beveled edges, as and for the purpose herein described and shown.

In testimony that I claim the foregoing I have hereunto set my hand this 8th day of April, 1880.
